Multivariate PLSC analysis between the clinical blood biochemistry tests and cognitive variables. Multivariate PLSC analysis correlating the clinical blood biochemistry tests to cognitive variables revealed one significant LV (p < 0.05), which accounted for 73.50% of the cross-block covariance. The pattern identified by the LV showed that lower Kt/V and hemoglobin were positively associated with lower IR-S and SR-S values in ESRD patients.

PLSC: partial least-squares correlation; LV: latent variable; Kt/V: kinetic transfer/volume urea; IR-S: immediate recall total score; SR-S: short-term delayed recall score; ESRD: end-stage renal disease.
